What is the value of j in the equation √ j √ j 14 = 3√ j 10?
Answers
Answer:
the value of j in the given expression is: 16
Step-by-step explanation:
we are given the expression as:
so on squaring both side we have .
Hence the value of j is 16.
The equation is:
√j + √j + 14 = 3√j + 10
2√j + 14 = 3√j + 10
14 - 10 = 3√j - 2√1
4 = √j
Now, we will square both sides of the equation:
4² = (√j)²
16 = j.
Therefore, j is 16.

Answer:
The height of the cliff is 81.6m
Step-by-step explanation:
Please see the attachment below for an illustrative diagram representing the situation.
Step-by-step explanation:
From the diagram
x = /AB/
The height of the cliff is given by ( x + 1.6m)
Considering triangle ABC which is a right-angle triangle
/AB/ is the opposite and
/BC/ is the adjacent ; /BC/ = 50m
Angle of elevation is 58°
Then, we can write that
Hence, Side /AB/ = 80.0m
Since, /AB/ = x
∴ x = 80.0 m
Recall, the height of the cliff is given by
x + 1.6m
= 80.0m + 1.6m
= 81.6 m
Hence, the height of the cliff is 81.6m
Answer:
80.02m
Step-by-step explanation:
Find the diagram attached. Using SOH, CAH, TOA to find the height of the cliff AC,
AC is the opposite side and BC is the adjacent
Given BC = 50m and ∠ABC = 58°
tan∠ABC = AC/BC
tan58° = AC/50
cross multiply
AC = 50tan58°
AC = 80.02m
Hence the height of the cliff is 80.02m

If David, Malachy and Paul share some sweets in the ratio 4:3:3 then Paul get 7.2 number of sweets
What is Ratio?
A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given that David, Malachy and Paul share some sweets in the ratio 4:3:3
All three shared 24 sweets together.
Let x be the number of sweets
4x+3x+3x=24
Add the like terms
10x=24
Divide both sides by 10
x=2.4
Now paul has 3x sweets so 3×2.4=7.2
Hence, Paul get 7.2 number of sweets

4x+3x+3x=24
10x=24
x=24/10
x=2.4
Since Paul=3X=3*2.4
=7.2
• hence the Paul get 7.2
